When you are in a budget or invoice, it does not matter which one. If I try to upload several files at the same time I can not, it fails and only the first file is uploaded. Also when uploading a file correctly, when I want to upload another file I can not and I get an error, I must update the page with F5 to continue uploading files.
I have version 1.5.8 and it happens to me since version 1.5.4. What is the problem?.
